Those are technically not database patches since they dont update binaries.
They are still procedures / pl/sql code that update underlying DB tables. We
conventionally call them DB patches to differentiate from application file
system patches that update only the application code tree.
Here the differentiator is the patches applied using opatch.
Thanks
